Can't jump while using View Navigation Walk
In Preferences, search shortcuts by name and look in 3D View &gt; 3D View (Global) &gt; (scroll way down) View3D Walk Modal

It's odd that it doesn't appear in search results when typing &quot;walk&quot; or &quot;jump&quot;.
The default jump key is V, but can of course be reassigned.
It may also be worth mentioning that once in the Walk Modal, Tab toggles gravity, Esc resets the camera to its original position, and Enter commits the new camera position.
